- In this version, it is not possible to carry more than one barysal pistol. No doubt, this is because I am still figuring out a lot of things about ZIL.
- The barysol pistol is limited to 6 charges. Additonal charges are "lost".
- When given the option of picking up one (or more), if you already have an existing pistol, you will be presented with an opportunity to transfer the remaining charge to your existing pistol.
- If you pick up a battery unit during the course of your adventure, pressing B or b will charge a barysal pistol, if you are carrying one. If you do so, the battery unit will be lost.
- Let me know if the above barysal pistol limitations makes completing the adventure difficult and/or impossible. I'll figure out another way to implement this. Thanks in advance!
Feel free to report bugs or any issues with this adaptation. Thanks!
